1. Monitoring ML Model Inference Performance with Datadog

    Python

    To monitor ML model inference performance with Datadog using Pulumi, you would typically want to set up custom metrics that can capture various aspects of your model's performance, such as latency, throughput, error rates, etc. These metrics will then be sent to Datadog, where you can visualize them on dashboards or set up alerts based on predefined conditions.

    For simplicity, let's assume that we want to track the average inference latency and the error rate. You would need to instrument your ML inference service code to measure these values and use Datadog's APIs to report them.

    The pulumi_datadog package provides resources to help you set up the Datadog monitors programmatically. The datadog.Monitor resource, in particular, can be used to create monitors that will watch the metrics you're interested in and notify you if they cross a certain threshold.

    Below, you'll find a Pulumi program written in Python that shows how you might set up such a monitor. Please note that you'll need to actually send the metrics from your application to Datadog separately, as the Pulumi program only sets up the monitor itself.

    import pulumi import pulumi_datadog as datadog # Define the metric name for inference latency and error rate latency_metric_name = 'my_ml_model.inference_latency' error_rate_metric_name = 'my_ml_model.inference_error_rate' # Create a Datadog monitor for average inference latency avg_latency_monitor = datadog.Monitor("avgLatencyMonitor", name="Average Inference Latency", type="metric alert", query=f"avg(last_5m):avg:{latency_metric_name} > 1000", message="Average model inference latency is too high. Please investigate.", tags=["environment:production", "team:ml"], priority=3, # Additional monitor options can be set here ) # Create a Datadog monitor for inference error rate error_rate_monitor = datadog.Monitor("errorRateMonitor", name="Inference Error Rate", type="metric alert", query=f"avg(last_5m):avg:{error_rate_metric_name} > 0.05", message="Model inference error rate is too high. Please investigate.", tags=["environment:production", "team:ml"], priority=3, # Additional monitor options can be set here ) # Export the IDs of the monitors pulumi.export("avg_latency_monitor_id", avg_latency_monitor.id) pulumi.export("error_rate_monitor_id", error_rate_monitor.id)

    In the above example:

    • We defined two monitors using the datadog.Monitor resource.
    • For the average inference latency, we created a monitor that triggers if the average latency over the last 5 minutes exceeds 1000 milliseconds.
    • For the inference error rate, we created a monitor that triggers if the average error rate over the last 5 minutes exceeds 5%.

    Remember, this is just the monitoring setup. You still need your ML inference application to send the actual metric data to Datadog.

    The threshold values (1000 for latency and 0.05 for error rate) should be adjusted according to what is acceptable for your specific use case. You might also want to add other conditions or use different time windows.
